Abstract: This article describes the application of digital pressure detection instrumentation and digital pressure detection instrumentation market capacity and trend analysis! The digital pressure detection instrument is an instrument that measures the physical pressure signal. The pressure measurement converts the physical signal collected by the sensor into an electrical signal, and then amplifies and filters the output signal of the pressure sensor through an external circuit. The /D converter converts to a digital signal that is processed by the microprocessor to implement the pressure measurement function.
First, the digital pressure detection instrumentation overview 1, the definition of digital pressure detection instrumentation Digital pressure detection instrumentation is the pressure of the physical signal measurement instrument, the pressure measurement is through the sensor to collect the physical signal into electrical signals, and then through the outside The circuit amplifies, filters, etc. the output signal of the pressure sensor and sends it to the A/D converter and converts it into a digital signal. The pressure measurement function is realized after processing by the microprocessor. There are two main application methods for digital pressure detection instruments. They are direct pressure measurement and comparison verification between pressure instruments. Direct pressure measurement mainly refers to the on-site pressure measurement of pipelines and pressure vessels; pressure calibration refers to evaluating the value indicated by a pressure meter or measurement system under the specified conditions by the corresponding pressure standard to reproduce the measured values. A pressure reference standard is used to assign values ​​to pressure instrumentation, and the pressure instrumentation values ​​are traced back to the values ​​reproduced by the pressure reference standard.
2. Application of digital pressure detection instrumentation Digital pressure detection instrumentation mainly meets two applications: First, it is used to measure the pressure of fluid in pressure vessels and pipelines. It is mainly used in industrial production for various gases in pipelines, The measurement of the pressure of liquid medium achieves the control of product, production and on-site safety through the measurement and control of various fluid pressures; the second is the verification of the pressure measuring instrument itself, and the accuracy of the detection instrument is effective for the above purposes. The important index reached. In digital pressure detection instrumentation, high-precision meter accuracy can be two to four times as accurate as low-precision meters, and high-precision meters can be used to verify low-precision meters.
The digital pressure detection instrumentation industry is an industry that provides measurement and inspection methods, methods, and control systems for modern society's production, life, and military fields. Digital pressure detection instruments and meters enable scientific and quantitative measurement in all areas of our production and life. The necessary means to achieve scientific understanding in the economic field.
II. Capacity and Trend Analysis of Digital Pressure Instrumentation Market In the past two years, the digital pressure detection instrumentation market in China has maintained a rapid growth rate. In 2009, the digital pressure detection instrumentation market capacity was 2.201 billion yuan, accompanied by GDP in 2010. With rapid growth, the market for digital pressure detection instrumentation has reached 2.494 billion yuan. Although the growth rate of petroleum, chemical, electric power, and metallurgical industries has slowed down in the next few years, the above industries will continue to grow on the basis of the continuous increase in China's total economic output. To maintain a stable growth of a certain extent, the market demand for digital pressure testing instruments and meters will continue to grow steadily in the next few years.
